Re: Free type "invalid glyphs"

[Danny Forrest]

Hello again,

I have found that FT_Get_Char_Index will explicitly return 0 for 'missing' characters which is the fix for the issue. I am using FT_Load_Char but should that really return a valid construct for an "invalid" character?

Thanks.

Subject: Free type "invalid glyphs"

 

Hey, I have currently begun the implementation of freetype for my job but come across the issue of unnecessary characters.

For various fonts it will present the rectangle for a glyph I assume it couldn't determine, but there are no errors and even the data is still filled in. 

Is there a way I can skip these characters without potentially having a map of all fonts and the dimensions a rectangle would present (which is still not desirable as some characters may actually meet those dimensions)?

Thanks
